“The subjects this morning that she will be unable to testify to…are the subjects of the relationship between Jack Abramoff and his associates and White House officials, including Ms. Ralston, and the subject of the use by White House officials of political e-mail accounts at the RNC,” Ralston’s lawyer, Bradford Berenson said, during the May 10 deposition. “She has material, useful information about both of those subjects.”

According to Waxman’s memo, which was sent to Oversight Committee members, Ralston is seeking immunity from prosecution.
